Patent GB-1184633-A (GB)
Title: Image Spectrophotometer.
Inventor: WHITE PETER GORDON
IPC: G01J3/28
Filed: 1968-02-16
Abstract: 1,184,633. Image spectrophotometer. TRW Inc. 16 Feb., 1968, No. 7730/68. Heading H4F. [Also in Division G1] The Specification describes apparatus whereby a viewed scene, Fig. 1, may be scanned and displayed at one or more wavelengths whereby visually similar objects, e.g. growing vegetation 13 and cut vegetation 22 camouflaging an object 15, may be distinguished by means of their different reflective spectral characteristics, Fig. 2. Thus an image of a strip portion 66, Fig. 7, of the scene is dispersed by refractive or diffractive means in a direction normal to the length of the strip and the resultant image, Fig. 8, scanned along one or more wavelengths (horizontal lines) the resulting video signal being used to intensity modulate linearly scanned cathode-ray tube display means. The strip portion 66 is selected by slit 31, Fig. 4, having the scene focused thereon by lens 32. The strip is diffracted by grating 35 and the image, Fig. 8, focused on camera tube 37. When the apparatus is used in an aircraft 60, Fig. 5, the movement of the aircraft, together with the synchronized oscillatory movement of mirror 30, Fig. 4, enables consecutive abutting strips of scene to be scanned by successive field scans of camera 37. The raster of camera 37 only need comprise a small number, e.g. twelve of lines since only a one-line scan of the correct wavelength will enable growing and cut vegetation &c. to be distinguished. The video signal from the camera resulting from such a one wavelength (line) scan, is fed to intensity modulate the line sweep of display 131, Fig. 11, the position of the line corresponding to the position of the strip 66 in the scene. A representation of the entire scene may thus be built up at said wavelength. Using three wavelengths (lines) and feeding the corresponding three video signals to the three modulating inputs of a three colour display tube 132, a corresponding colour display may be produced. By selecting the relative intensities of the colours, growing vegetation may show as white and cut vegetation as red. The video signals may alternately be stored at 130 or digitally analysed and stored by means 140 and 141. Compensation for the non-linear characteristic, Fig. 13 (not shown), of the camera tube 37 may be carried out by computer 155 and the normalized digital data stored at 156. To increase the wavelength resolution of the apparatus, the camera raster may be compressed in the frame direction, Fig. 10 (not shown). Mechanical details of the apparatus are given, Figs. 14, 15, 16, 17, 18, 19 (all, not shown).

Title: Improvements in or relating to magnetic means for the hardness testing of metals
IPC: G01N27/72
Filed: 1940-04-30
Abstract: 581,964. Photo - electric apparatus. STANDARD TELEPHONES & CABLES, Ltd., and STOCKS, H. R. April 30, 1940, No. 7800. [Class 40 (iii)] [Also in Group XXXVI] A machine for the continuous sorting of magnetizable objects such as rifle and machinegun bullets in accordance with hardness, includes means for comparing the remanence of of each object in turn with that of a standard, and means operated by the comparing means for directing the object during discharge. On one arm of a balance BAL is a mirror TM forming part of an optical system which includes . a light source, a fixed mirror FM, and a photoelectric cell of the split type. The coils TC are in series and are supplied with current through one of the contact sets CS for a fraction of each cycle. They are so connected that they have polarities similar to the lower ends of the two bullets, so that if the flux densities of the bullets are equal the two coils are repelled by equal forces and no deflection of the balance takes place. If the bullet under test has a greater flux density than the standard bullet, the balance BAL is forced against a stop AS, which prevents motion of the balance. If the tested bullet is weaker, the balance BAL is deflected in a clockwise direction and causes the image of the light source to deflect from its position at the junction of the photo-electric cell on to one half of the cell and the resulting' output of the cell operates an electromagnet controlling the bullet-deflecting member, which is operated after a delay corresponding to the time taken for the bullet to travel from the rotating drum to the shoot.

Title: Improvements in or relating to diecasting and moulding machines
Inventor: JONES WILLIAM HENRY
IPC: B29C45/84
Filed: 1962-03-01
Abstract: 956,814. Casting-machines. HIGHWOOD ENGINEERING CO. Ltd. Feb. 20, 1963 [March 1, 1962], No. 7969/62. Heading B3F. [Also in Division B5] In a die-casting or moulding machine an elongated member 22 moves with the movable die platen 11 and carries a number of spacedapart locking elements 23 which are movable to project from the member 22 and be engageable with a part of the machine not movable with the platen 11 if the latter inadvertently tends to move towards the fixed platen 10 so as to prevent such movement. In operation, with the dies open a movable die guard 32 is moved into position covering the dies, an abutment 35 actuating an air valve 36 to supply pressure air to a cylinder 29, raising a member 27 to lift the locking members 23 to the inoperative position, thus allowing the dies to close upon actuation of a valve 21 by the operator. After casting, initial displacement of the guard 32 releases the valve 36 and the member 27 falls to its lower position, allowing the guard 32 to be completely opened. A member 34 engages the member 27 in its uppermost position. The valve 21 is then actuated to open the dies and as the elongated member 22 moves rearwardly with the platen 11 the locking members 23 are successively moved to the operative position by a cam surface 31. If at any time during opening of the dies, removal of the casting &c. a fault develops in the hydraulic system or the valve 21 is accidentally operated, a closing movement of the platen 11 causes one of the members 23 to engage a lever 24, thus actuating a valve 25 to cut off the supply of pressure fluid to the die-closing piston 17.
